High-strength reusable and recyclable underwater adhesive
Stanford researchers at the Bao Lab have designed hydrophobic perfluoropolyether (PFPE) polymers that can be applied in underwater conditions, at room temperature, without any solvent or curing steps, and can be reused and recycled.
Unlike other approaches which use bio-inspired designs, this method uses dynamic polymers with a strong hydrophobic backbone that can be applied in fully underwater conditions to polyimide, glass, and steel substrates.
Stage of Development
Applications
- Biomarine or biomedical application in which adhesion to wet surfaces is required
- Especially useful when adhesion needs to be repeatedly adhered and de-adhered or the adhesion needs to be done quickly
Advantages
- Hydrophobic
- Similar performance in both dry and underwater conditions
- Strong adhesive - 0.26 MPa within an order of magnitude of the best reported underwater adhesives
- Rapid and simple application - 2 seconds of light pressure- no need for a long curing time
- Can be recycled and reused
